solid pressure
|
pressure= force/ area
Pa= N/ m2 smaller area, pressure higher bigger area, pressure lower |
|
|
Liquid Pressure
|
pressure= height x density x gravitational pull
Pa = h x "rho" x g |
|
|
Properties of Liquid Pressure
|
1) Pressure acts in all direction
2) Pressure at the same level is equal 3) Pressure finds it's own level 4Pressure increased with depth |
